Submitted by: Mike Topor
Taxon: Hyperoblastus sp.
Submit date: 2008-03-30
Location (approximate): Thedford, Lambton, ON
Stratigraphy: Widder Formation
Age: Erian (Middle Devonian)
Submitter notes: This cluster of small blastoids is from the Rock Glen Sub member beds of the Widder Formation. Small size is typical for this un-described species, although it is closely equivalent stratigraphically (slightly higher) to the New York species H. goldringae. All of the specimens are 5-6mm in height and are on the large side. Most specimens are smaller.
